The extreme kindness demonstrated by Ruth is almost self-effacing, and cannot be used as a model emulated by regular people. What, then, is the purpose of this book?

Ruth is the matriarch of the dynasty of David. The nature of monarchy can lead to the king's misuse of his power to promote his own interests, at the expense of the nation. Extreme kindness, chessed, and concern for others, can protect the king from corruption. Ruth presents a model that can defend a king from his own strength, and ensure that the king channels his powers for the good of the nation.
